The object of this invention vis e 'povide ferred form of a frame or chass1s, on whichV one or more rotary hoeing devices are mounted and driven b suitable motive power on the machine, t ejwhole being so balancedl that the o erator may control the depth of cutnof the oes, as we will proceedl now to explain and finally claim.

In they accompan in drawin illustrating the invention, 1n t e severa figures of which like parts are similarly desi ated, Figure 1 is a -to -plan view, and F1 2' is a side elevation, i lustrating one embo 'ment of the invention. Fig. 3 is a front elevation Theframe or chassis 1, may be of any a proved construction and material, prefera ly `stock an le metal, and it may be vof truncated w ge shape in plan view as shown in Fig. 1, or of other suitable configuration. For strengtheningp y oses therear of the frameor chassis may braced-by the cross-braces 2. The frame' or chassis fsa also may be provided with the elevated handle member 3 for the use of the operator in guiding and manipulating the machine. This rear end also may have the groundrest members 4. The frame or' chassis is mounted on an axle 5 havin a air of wheels 6, although any number o w eels may be .use

7 is a motor of an suitable construction and power, mounte -upon the frame or chassis, andprovided with a shaft 8 extendingl longitudinally forward of the frame or chassis and there mounted ina bearing 9. At its front end the shaft is provided with a worm 10 which is in mesh with the worm wheels 11. These worm wheels 11 are fixed to upright shafts 12 which are mounted in sleeve-11 e housin 13 secured to the front of the frame or c assis Aby brackets 14 and stays 15, and these housings preferably are kinclined toward one another at the top.

The shafts 12 are provided` on their bottoms with the hoes 16, herein shown as twobladed implements, adapted to be rotated in o posite directions.

T e blades ofthe hoes are herein shown as radiating from common hubs 17 which are arranged to turn with the shafts 12. Each hoe lade is curved longitudinally `and inclined transversel i in l order to function eiciently. lW'here t e hoes are used 1n palrs,

their blades follow one another in the cycle of rotation.

0f course, the machine may be equipped with only one hoe, or it may be equipped with two or more hoes'.

As power is applied, the hoes are rotated and by contact with the earth serve to move or propel the machine. p

The shaft bearing 9 and the sleeve-like housings! 13 may be provided respectively with grease cups 18 and 19.

Cross-bars 20 fixed to the .frame or chassis may be used to support the motor, and one of these cross bars may support a rear bearing 21 forthe shaft 8. y

An operatorjgrasping the handle 3 is able `to uide the machine in its work in the eld or etween plants or trees, and he is 4also tion of rotation of the hoes.

able to raise or lower the hoes so as to cut less or more deeply into the soil.

The machine runs `equally well toward or from the operator, dependmg on the direc- When the machine is running toward the operator he has A the advantage of walking on unbroken or relativel level ground.

The b ades of the hoes are set to balance the resistance of the earth, and as they stand at an angle they catch deeper and stronger in the soil at their lower and inside po1nts than at theirouter portions, and so move the machine in a direction opposite to that in which they are turning. When nicely ad- More blades at the same angle may be I used for larger and heavier machines.

The operator YisY able to ut upon the hoes the-pressure suieient to keep them in operative de th `o cut, as desired. i

ariations in the details of construction are permissible withinthe principle ofthe' invention and the scope of the claims' following. Whatwe claim is 1. A hoeing machine, comprising a wheeled frame and carrying a motor, a horiposition, as well as to regulate thelr f zontal shaft driven by said motor and extending to the front'of the machine, and an upright rotary hoeing device dependingly mounted on the front of the machine and in operative connection with the said shaft and having radially arranged blades curved longitudinally and inclined transversely and thereby adapted to engage the earth to move the machine and stir up the earth.

2. A hoeing machine, comprisin a wheeled frame and carrying a motor, a s aft driven by said motor and extending to the front of the machine, and an upright rotary hoeing device de endingly mounted on the front of the mac ine and in operative connection with the said shaft, said hoein device comprisino' radially arranged b ades having inclinedJ earth-engaging active surfaces. Y

3. A wheeled hoeing machine, provided with a shaft connected with the motor and extending forwardly, a pair of downwardly divergent shafts mounted on the front of the machine and haviugbladed hoes at their gearing connecting n Lacasse frame and having a shaft extending fori a wheel mount therefor, the plane of connection of the mount with the frame being such that the frame is nearly balanced, a motor mounted on the frame and having a shaft extending forwardly of the frame and provided with a worm, upright shafts mounted on the front of the frame and diverging downward and having on their lower ends bladed hoes and on their up er ends worm wheels, said wheels meshing with the worm on the motor shaft, and hand guiding means at the rear of the machine.

In testimony whereof we have hereunto set our hands this 8th day of November, A. D.,
